SUMMARY
Radiological Environmental Monitoring Program The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for Palisades Radiological Environmental Monitoring Program (REMP) for the period January 1 through December 31, 2024. This report fulfills the requirements of Palisades Technical Specification 5.6.2.
No measurable levels of radiation above baseline levels attributable to Palisades operation were detected in the vicinity of Palisades in 2024. The 2024 REMP thus substantiated the adequacy of source control and effluent monitoring at Palisades with no observed impact on the environment from plant operations.
Palisades established the REMP prior to the station becoming operational to provide data on background radiation and radioactivity normally present in the area.
Palisades has continued to monitor the environment by sampling a variety of environmental media as well as measuring direct radiation. All analyses have required nuclide specific lower limit of detections (LLDs) which must be achieved.
The requirements of the REMP are formally described in the offsite dose calculation manual (ODCM), a site-specific regulatory document. The REMP was modified in 2023, which is discussed in more detail in Section 1.4.
The REMP includes sampling at indicator and control locations. The REMP utilizes indicator locations near the site to determine if any increases of radioactivity has occurred due to station operation and control locations farther away from the site to indicate the presence of only naturally occurring radioactivity. Palisades personnel compare indicator results with control and preoperational results to assess any impact Palisades operation might have had on the surrounding environment.
In 2024, REMP samples were collected for radiological analysis. The results of indicator locations were compared with control locations and previous studies. All 2024 REMP results support the conclusion that the surrounding environment is not adversely affected by Palisades' radiological effluents. No activity in any REMP sample from 2024 was attributed to Palisades' radiological effluents.
Reporting Levels No samples equaled or exceeded reporting levels.
1.3 Sample Deviations During 2024, environmental sampling was performed for five media types (airborne, surface water, drinking water, sediment, and fish) and analyzed for radionuclides. All REMP samples were obtained and analyzed in accordance with the Offsite Dose Calculation Manual (ODCM) in 2024.

Page 4 of 98 Annual Radiological Environmental Operating Report Program Modifications There was only one ( 1) program modification made in 2024. The control air sample (GR10) was lost due to the vendor not supporting the maintenance and sample change out. This occurred at the end of November. A new control location was established (12) at the Palisades Emergency Operating Facility in Benton Harbor.
This loss resulted in a loss of 2 weekly air samples for this location which is documented in Attachment 1. This is in alignment with NUREG-1301 with the update to the ODCM in progress.
INTRODUCTION Radiological Environmental Monitoring Program Palisades established the REMP, as defined in the ODCM, to fulfill the requirements of 10 CFR Part 50 Appendix I Section IV.B.2. The REMP supplements the radiological effluent monitoring program by verifying that the concentrations of radioactive materials and levels of radiation found in the environment surrounding the plant are consistent with the effluent measurements and the modeling of the environmental exposure pathways.
Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways are monitored as required by Palisades ODCM. These requirements are also listed in this report in Table 1 through Table 4.
Section 4.0 of this report provides a discussion of 2024 sampling results and Section 5.0 providing a summary of results for the monitored exposure pathways.
2.3 Land Use Census Palisades conducts a land use census annually to identify exposure pathways and changes in uses of land within 5 miles of the site from the previous year that might require modifications to the REMP and the ODCM. The purpose of this census is to identify critical receptor pathways for the purpose of effluent modeling and REMP sampling.

Page 12 of 98 Annual Radiological Environmental Operating Report 4.0 INTERPRETATION AND TRENDS OF RESULTS 4.1 Air Particulate Sample There were 316 air samples collected and analyzed for gross beta during 2024. Air particulate samples are collected weekly from six (6) air-sampling locations, five (5) of which are indicator locations and one (1) is a control location. During the weekly collection, an "as found" and "as left" leak test is performed at each station. Weekly samples are sent to Teledyne Brown Engineering Environmental Services for analysis.
Analysis of the airborne particulate sample data, between the five (5) near-site indicator locations and the control location, validates that the surrounding environment is not adversely affected by Palisades' radiological effluents. The average concentration of gross beta activity among all indicator locations was 2.43E-02 pCi/m3 and was 2.41 E-02 pCi/m3 for the control location. Gamma isotopic analysis is performed quarterly on a quarterly composite of the weekly filter papers. All radionuclides detected were naturally occurring radionuclides which are not attributed to plant radiological effluents.
Palisades' pre-operational environmental study showed naturally occurring gross beta radiation between 0.03 and 3.0 pCi/m 3 with a similar trend between stations onsite, in the surrounding community, and control stations. The activity results from 2024 indicate there is no measurable change between pre-operational airborne gross beta activity and present day airborne gross beta activity.
In the absence of plant-related gamma radionuclides, gross beta activity is attributed to naturally occurring radionuclides. The air sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2024. This conclusion is that the surrounding environment is not adversely affected by Palisades' radiological effluents. No REMP air samples from 2024 contained measurable radiological materials attributed to Palisades' radiological effluents.

Page 13 of 98 Annual Radiological Environmental Operating Report 4.2 Thermoluminescent Dosimetry (TLD) Sample Results Palisades reports measured radiation dose as net exposure (subtracting control reading) normalized to 91 days. TLDs are oriented in an inner ring, outer ring, and a control location. The inner ring consists of 11 TLDs, the outer ring consists of nine (9)
TLDs, and there is one (1) control location. This orientation allows for monitoring all nine (9) overland compass sectors surrounding Palisades. To assess the effect of direct and shine radiation from Palisades to the environment, each location is compared to a baseline of historical data which was created from a comprehensive review of results from January 2019 through December 2023 for each location. A result outside three (3) standard deviations of the historical mean is indicative of dose attributed to operation of the plant and a follow-up investigation is performed to evaluate the cause.
At the beginning of the third quarter, the transient dose was performed differently than the previous two quarters. Previously, a vault study was performed, and a daily dose was calculated and attributed to the dose received during shipment (transient). At the beginning of the fourth quarter 2024, the vault study dosimeters were sent with the new field dosimeters as usual but were immediately sent back with the third quarter field dosimeters after being changed out to account for dose received during shipment to and from the vendor. This is more representative of the dose received during transient and resulted in significantly lower dose than the previous calculated daily dose. As a result, the net exposure was lower in the 3rd and 4th quarters than the first two quarters. During 2024, none of the TLD values indicated a dose attributed to Palisades plant operation or activities.
During 2021, four additional locations were added (identified as 4-21, 5-21, 9-21, and 11-21) to establish a new baseline at these locations. Starting in the first quarter of 2022, locations 4, 5, 9, 10, 11, and 12 were discontinued and locations 4-21, 5-21, 9-21, and 11-21 were implemented into the program. Essentially this resulted in a relocation of three of the outer ring TLDs, a relocation of one of the control TLDs, and a discontinuation of two control TLDs. All changes made were in accordance with the ODCM and the ODCM change process (technical specification 5.5.1 c.). As a result, these locations do not have a full five (5) years of historical data in which to create a baseline.
TLD measurements taken as part of Palisades' pre-operational environmental study used different instrumentation, which had difficulty in achieving desired sensitivity and accuracy. A more sensitive type of TLD was implemented in 1971 and the present day TLD device used is the industry standard. TLD data has trended consistently throughout the several most recent independent spent fuel storage installation (ISFSI) loading campaigns which indicates that these loading campaigns have had no measurable effect on the environment.

Page 14 of 98 Annual Radiological Environmental Operating Report 4.3 Waterborne Sample Results 4.3.1 Surface Water 4.3.2 During 2024 Palisades implemented the REMP in accordance with the ODCM for collection of surface and drinking. For all surface and drinking water samples the same control location is used as a baseline for comparison. That control sample location is referred to as the "Ludington Control" and is collected 125 miles (201 km) north of Palisades. The Ludington Control sample is analyzed monthly and is a composite of daily samples. The Ludington Control sample is analyzed for gamma, tritium, and gross beta activity. In 2024 the only radionuclide activity detected in Ludington Control water was naturally occurring isotopes. Of the twelve (12)
Ludington Control samples collected in 2024, five (5) contained detectable gross beta with an average value of 3.08 pCi/L. The gross beta activity is a result of naturally occurring radionuclides and is not attributed to Palisades' radiological effluents.
The indicator surface water samples collected and analyzed for the REMP include "Lake In" water. This sample is Lake Michigan water after it has traveled through the Palisades' intake structure and traveling screens. This sample is collected daily and composited into a monthly sample which is analyzed for gamma radionuclide and tritium weekly onsite. This sample is also analyzed by Teledyne Brown Engineering Environmental Services for gamma, tritium, and gross beta activity monthly. All radionuclides detected were naturally occurring and are not attributed to Palisades' effluents. Five (5) out of the twelve (12) monthly samples contained measurable gross beta with the average detectable gross beta activity at 4.36 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide.
Palisades' pre-operational environmental study established a baseline of gross beta activity for the site before Palisades was operational. The study results for surface water showed consistently measurable results for gross beta activity between 11 - 18
(+/- 5) pCi/L.
The surface water sample results collected in accordance with the REMP are consistent with the calculations and methodologies of the effluents monitoring program for 2024. The results indicate that the surrounding environment is not adversely affected by Palisades' radiological effluents. No REMP surface water samples from 2024 contained measurable radiological materials attributed to Palisades' effluents.
Drinking Water The indicator drinking water samples collected and analyzed for the REMP include "Domestic Water" and "South Haven Drinking Water". All samples are analyzed for gamma isotopic, tritium, and gross beta by Teledyne Brown Engineering Environmental Services.
Plant: Palisades Year: 2024 I
Page 15 of 98 Annual Radiological Environmental Operating Report Domestic Water is collected onsite from a potable water system. This sample is collected daily and composited into a monthly sample which is analyzed for gamma radionuclide and tritium onsite. All radionuclides detected were naturally occurring and are not attributed to Palisades' radiological effluents. Four (4) out of the twelve
( 12) monthly samples contained measurable gross beta activity with the average detectable gross beta activity at 2.93 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide. Domestic water is not required by the ODCM for the REMP. This sample is collected as part of the NRC bulletin 80-10 commitments and is included in this report because the data strengthens the REMP.
South Haven Drinking Water is collected from the City of South Haven Water Treatment facility located in South Haven, Ml. All radionuclides detected were naturally occurring and are not attributed to Palisades' radiological effluents. Eight (8) out of the twelve ( 12) monthly samples contained measurable gross beta with the average detectable gross beta activity at 2.82 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide.
Palisades' pre-operational environmental study established a baseline of gross beta activity for the site before Palisades was operational. The study results relied upon as a baseline of surface water and gross beta activity between 11 - 18 (+/- 5) pCi/L.
The drinking water sample results collected, in accordance with the REMP, support the conclusions of the effluents monitoring program for 2024. This conclusion is that the surrounding environment is not affected by Palisades' radiological effluents.
4.3.3 Well Water Palisades samples one (1) offsite well water location. This sample is not required by Palisades' ODCM but is procedurally implemented to strengthen the program overall.
The REMP well water sample is collected offsite from a neighboring community and is identified as, "Palisades Park Commercial Well Water". This sample is collected once per month as a grab sample from a community just south of Palisades while the facility is operational (summer months). This sample is analyzed for gamma, tritium, and gross beta activity by Teledyne Brown Engineering Environmental Services. In 2024, no radionuclides were detected in this sample, including tritium. One (1) out of the five (5) monthly samples contained measurable gross beta with the average detectable gross beta activity at 4.60 pCi/L. The gross beta activity is attributed to naturally occurring radionuclide. Sampling was performed from May through September 2024.
Palisades' pre-operational environmental study established a baseline of gross beta activity for the site before Palisades was operational. The study results were that five well water samples from Palisades contained gross beta activity above 5 pCi/L with the highest value being 16 pCi/L.
The well water sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2024. This conclusion is that the surrounding environment is not adversely affected by Palisades' radiological effluents.
No REMP well water samples from 2024 contained measurable radiological materials attributed to Palisades' radiological effluents.
Plant: Palisades Year: 2024 I
Page 16 of 98 Annual Radiological Environmental Operating Report 4.4 Sediment Sample Results 4.5 Sediment samples are collected two (2) times per year, north and south of the plant from the beach on Lake Michigan. One sample is collected at the southern edge of the property and a second sample is collected approximately 0.5 miles north of the plant at Van Buren State Park. The sample south of the plant is not required by the ODCM but is collected and analyzed to strengthen the REMP. Both the north and south sediment samples are analyzed for gamma radionuclides. In 2024, only naturally occurring radioisotopes were detected, which are not attributed to Palisades' radiological effluents. In accordance with the ODCM, no control sample is collected for this sample type.
Soil samples were not specifically part of the Palisades' pre-operational environmental study, however a soil study of Cs-137 was performed by Palisades in 2011 (due to global events such as historical atomic testing and fallout). Analysis was performed of soil in the surrounding area (Southwest Michigan) which showed Cs-137 concentrations between 1.41 E-08 uCi/g and 5.68E-07 uCi/g with an average of 2.68E-07 uCi/g. Considering similar studies performed by other utilities, a conservative (low) background of 1.8E-07 uCi/g Cs-137 in soil is assumed to be due to global fallout.
The sediment sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2024. This conclusion is that the surrounding environment is not adversely affected by Palisades' radiological effluents.
Ingestion Sample Results Fish Sample Results Indicator and Control fish samples are collected and analyzed twice per year. The filet of the fish is shipped to a vendor and analyzed for gamma radionuclides. The indicator fish are collected near Palisades lake-out discharge point. At least two (2) species of commercial or recreational importance are collected and analyzed. At least one (1) sample of the same species is collected as a control sample. The control fish are collected 201 km north of Palisades near Ludington, Ml. In 2024, the only radionuclides detected among all fish samples were naturally occurring radionuclides which were not attributed to Palisades' radiological effluents.
Palisades' pre-operational environmental study established a baseline for radiological material in fish. The study established that gross beta activity is generally between 2 and 4 pCi/g and gross gamma activity is generally between 0.04 and 0.4 pCi/g in fish.
Cs-137 and Sr-90 were measured in the pre-operational study and were expected to be measured due to known worldwide contamination from historical global atomic testing. Cs-137 detected was generally between 0.10 and 0.25 pCi/g and Sr-90 detected was generally between 0.01 to 0.04 pCi/g in the pre-operational environmental study.
The fish sample results collected in accordance with the REMP support the conclusions of the effluents monitoring program for 2024. This conclusion is that the surrounding environment is not adversely affected by Palisades' radiological effluents.

Page 17 of 98 Annual Radiological Environmental Operating Report 4.6 Land Use Census Results 4.7 The latest land use census (performed in August 2024) did not identify any changes that would prompt a change to the REMP or ODCM. The method used to perform the census was in accordance with the ODCM and site procedures. The sectors in Table 5 include all overland compass sectors.
In accordance with the REMP, the census was restricted to 2.5 miles after it was confirmed that the existing cow and goat in the ESE sector would be the critical receptor (for dose modeling purposes). Even if a cow or goat were identified greater than 2.5 miles from Palisades in the other sectors, the nearer goat and cow would be used (due to the higher consequence) to calculate dose to the public.

Facility lost power to a section due to a short in an underground feed.
TLD #2 found on the ground approximately 5 feet from the hanging location.
Air sample station 5PR was found not running.
Monthly composite water REMP water samples for October 2023 were not analyzed in time to meet La-140 LLD requirement. This was not discovered until 6/19/24 Evaluation/ Actions A new control air sample location was identified and established ( 12) at the Palisades Emergency Operating Facility (EOF) on 12/9/2024. Data from DC Cook is available for use if needed.
The air sampler was operated using a portable generator and thus had lower than usual total flow for the week as a result. The underground feed to the building that controls the air sample was repaired on 11/5/24.
The TLD was sent to the vendor for analysis and the new quarterly TLD was hung.
Troubleshooting resolved the issue and power was restored on 6/11/24.
Samples were collected and composited as required by the ODCM but shipment to the vendor for analysis was delayed. The required LLD for La-140 is 15 pCi/L and the MDC range of the three samples were:
20.15 and 20.31 pCi/L.

ND ND ND ND ND ND ND ND ND ND ND ND ND ND ND ND ND ND ND ND ND Transient dosimeters were shipped with the new quarter's dosimeters and returned with the previous quarter's dosimeters. Therefore, almost the entire dose received was from transportation vs calculating a daily dose from a vault study. This resulted in a lower transient/
daily dose being subtracted from the control dose.

The TBE Laboratory analyzed Performance Evaluation (PE) samples of air particulate (AP), air iodine, milk, soil, vegetation, and water matrices that represent test & matrix combinations available for REMP programs. The PE samples supplied by Analytics Inc., Environmental Resource Associates (ERA) and Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria:
A.
Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of TBE's result and Analytics' known value. Since flag values are not assigned by Analytics, TBE evaluates the reported ratios based on internal QC requirements based on the DOE MAPEP criteria.
B.
ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the US EPA, National Environmental Laboratory Accreditation Conference (NELAC), state-specific Performance Testing (PT) program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.
C.
DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values. MAPEP defines three levels of performance:
Acceptable (flag = "A") - result within +/- 20% of the reference value Acceptable with Warning (flag = "W") - result falls in the +/- 20% to +/- 30% of the reference value Not Acceptable (flag = "N") - bias is greater than 30% of the reference value Note: The Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which do not always resemble typical environmental samples obtained at commercial nuclear power facilities.
For the TBE laboratory, 124 out of 131 analyses performed met the specified acceptance criteria. Seven analyses did not meet the specified acceptance criteria and were addressed through the TBE Corrective Action Program. A summary is found below:
- 1.
The MAPEP February 2024 Soil Ni-63 result was evaluated as Not Acceptable. TBE's reported value was 294 Bq/kg and the known result was 1130 Bq/kg (range 791 - 1469).
The sample was reprepped by a different (senior) lab technician with results of 1120 &
1250 Bq. It was determined that there was a difference between the two techs during the sample prep (technique) and the procedure was revised to reflect these differences

- 2.
The MAPEP February 2024 vegetation Sr-90 result was evaluated as Not Acceptable.
The reported value was 0.05 Bq (not detected) and the known result was a "false positive".
This was considered to be a statistical failure because TBE's reported result with 3 times the uncertainty resulted in a slightly positive net result (0.03194 Bq/kg). The reported result was significantly below TBE's average detection limit for vegetation samples.
(NCR 23-09)
- 3.
The ERA RAD February 2024 water Ba-133 result was evaluated as Not Acceptable. The reported value was 26.0 pCi/L and the known was 22.3 (acceptance range 17.1 -25.8 pCi) or 117% of the known (acceptable for TBE QC). The sample was used as the workgroup duplicate with a result of 25.4 (114%). The sample had also been counted on a different detector with a result of 21.9 (98% ). The was TBE's first failure for Ba-133.
(NCR 23-10)
- 4.
The MAPEP August 2024 soil Fe-55 result was evaluated as Not Acceptable. The reported value was 346 Bq/kg and the known result was 1280 (acceptance range of 896-1664 Bq/kg). This was TBE's initial evaluation for Fe-55 in soils. The result was received at the end of December and the root cause in under investigation. No client samples were associated with this cross-check. (CAR 23-31)
- 5.
The Analytics September 2024 milk Sr-90 result was evaluated as Not Acceptable. The reported result was 7.28 pCi/L and the known result was 12.8 (57% of known). This sample was used as the workgroup duplicate and the carrier yields for both samples were 107% and 75%. The LCS recovery for the workgroup was at 106%. The ERA drinking water Sr-90 cross check that was analyzed around the same time was acceptable at 108%. There was no explanation for the failure. This is the first low biased failure for Sr-90 milk. The last failure (high) was in 2016. (NCR 23-24)
- 6.
The ERA RAD October 2024 water Gross Alpha result was evaluated as Not Acceptable.
The reported result was 53.2 pCi/L and the known result was 70.6 (acceptable range of 54.0 - 87.2 pCi/L). The reported result was the workgroup duplicate and was within 75%
of the known value (within TBE QC range). The original result was 63.3 pCi/L (90% of the known). Because the LCS result was biased slightly high, the decision was made to report the lower value. (NCR 23-20)
- 7.
The ERA RAD October 2024 water 1-131 result was evaluated as Not Acceptable. The reported value was 23.5 pCi/L and the known result was 29.7 (acceptable range of 25.8 -
33.6) The reported result was 79% of the known, which is within the acceptable TBE QC range. The workgroup was reviewed with no anomalies found. The LCS/LCSD results were 109% and 86.1 %. The sample was not processed in a timely manner as per the ERA instructions which stated to analyze shortly after receipt due to the short half-life.
Going forward, the QA &/or Lab Mgr. will ensure that this analysis is started sooner.

The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.
Thermoluminescent dosimeters (TLDs) are analyzed by an offsite vendor, "Environmental Dosimetry Company" (EDC). The TLDs used are Panasonic 814 Environmental dosimeters. EDC implements an internal quality assurance program and audits the program annually. There were no findings from the 2024 audit. An external audit of EDC was performed in 2024 which also resulted in no identified

Page 96 of 98 Annual Radioloaical Environmental Operatina Report Page 3 of 3 lnterlaboratory Comparison Program Results findings. Some of EDC's vendors also perform independent testing on the TLDs accuracy and precision. During 2024, 100% (72/72) of the individual dosimeters met the criterion for accuracy and precision. Also, 100% ( 12/12) of the dosimeter sets met the criterion for mean bias and precision and 100% (10/10) of independent blind testing passed the performance criteria for mean bias and precision.
Acceptance criteria for mean bias is +/-15% and for precision is +/-12.8% in accordance with EDC Quality System Manual
